C4D R20 fields are already proving to be a great addition to C4D’s toolset. Fields entirely replace C4D Falloffs, but the best part is that you can use Fields almost anywhere. A new quick tip from Maxon’s Jonas Pilz shows how you can use them to keep your selections parametric.
Polygon selections are great when you need to apply multiple materials to the same object. The problem with polygon selections is that they inherently are static. Not to worry, you can convert a polygon selection to a parametric one by merely using fields. Enabling the “Use Fields” checkbox and deleting the default Freeze, you can create a viewport widget that you can alter interactively changing your selection. Great!

There is one main force present by default inCinema 4D's dynamic system, and that is global gravity.Gravity always pulls the object towards the minus Y axis, downward, so to speak.Let's see this one more time.I'll create a sphere, right click, go tothe Simulation tags sub-menu and add a rigid body.I will lift my sphere just above the horizon.Add a floor.Right-click.Simulation.
Rigid body.Change the display, just for clarity, and press Play.You will see that sphere goes downwards.In order to access this global gravity setting, we have togo to the Edit menu, and bring up the Project Settings.In the Project Settings, the Dynamics tab, General sub-tab,and down here you can see it says Gravity.Currently, and by default, it's set to 1,000 centimeters.That is nothing more than rounding up of 981 centimetersby second squared which is the gravity acceleration of the earth at the equator.
The good thing is that we can change this.So, let me get rid of the floor, so we can see that sphere falling for a bit more.I would change my camera view.And I will press Play.So, this is the current acceleration because of the global gravity force.If I go to my Project Settings > Dynamics > General > Gravity, if I change thisto 25 and press Play, you will seethat the sphere accelerates, but a much slower rate.So it's basically, it's accelerating by 25 centimeters by seconds squared.
The other thing we can actually do is put a negative number here.If I put minus 1,000.Which is exactly the opposite of plus 1000.If I turn around and face the sphere from the bottom up,and press Play, you will see that the sphere is falling upwards.This way we can simulate effects like buoyancy,bubbles going up in the water and so forth.
In Cinema 4D, you can create 3D animation using Mograph, or you can add dynamics tags and let the simulations do the work. But how do you combine the two? In this video, I dig into exactly that topic, by going over how I created an animation where a brick wall stacks up using MoGraph techniques, and then explodes with realistic physic and gravity using Dynamics Tags!
Topics include MoGraph animation, working with effectors such as plane and random, animating effector falloff, creating and extruding text, and additional Cinema 4D MoGraph Animation Tips and Tricks.
